But that's just what a game is. It's a story created by the developers that you play and experience for yourself. What you're asking for isn't a game. It's a simulation. It wouldn't be interesting at all unless it had some base story to it that you can follow. It would be pretty muck like playing free roam in AC or Prototype and not having any missions. You would have no true objectives, thus no true rewards in that game. And to make objectives for the game, you would have to either implement story, or make small meaningless tasks such as taking the garbage out or something. I would much rather take the story over jumping onto a game just to eat some spaghetti and take out the trash. And flying to other planets/galaxies? How could you possibly find long-term entertainment out of flying to Saturn or Glise 581g with no type of story line? It would just be like playing skyrim and having all questlines finished, and just traveling between cities. Boring. But, if you're asking FOR there to be some story invoked, but allow you to have a s*** ton of freedom with it, 1 mission alone would be a tremendous load to try and make. Because the developers would have to take into effect every single possible action you could do to complete that mission, along with every single result to every single action you complete, and that's not counting other miscellaneous actions you'll probably do within the mission itself, or out of the mission. And you're also asking to be able to make a gun company, or a giant group, or etc.? Wow. This game would be never-ending with what you're asking to be out into it. Now that I'm thinking about it, id be surprised if this game was finished and released within a 20 year window. What you're asking for in a game is almost impossible, as nobody in the entire world probably has the amount of patience and work it would take to make a game like this. But you say you'll make it? Have fun with that, sport.
